Designed for the Standard-Portabel sector, the PJ557D model from Viewsonic features 2200 ANSI lumens, a native XGA 1024 x 768 resolution and a contrast ratio of 2000:1. The manufacturer specifies a runtime of 3500 hours for this projector's lamp. Looking at practical performance, up to 408 cm can be illuminated with 2200 ANSI lumens in dark environments. Once daylight is in the room, the image should ideally be no wider than 272 cm. The projector was released in 2007 and is officially no longer distributed by Viewsonic.
